The Voigtlander Nokton 50mm f/1.1 Lens is a high speed aspherical lens for VM lens mount rangefinder cameras. The lens is constructed with 7 elements in 6 groups, accepts 58mm filters and has as a minimum focusing distance of 3.28' (1m). This very fast and sharp lens weighs less than 16 oz., features an all-metal lens barrel construction, and a 10 bladed aperture diaphragm which creates pleasing out-of-focus highlights. Click stop aperture movements at half-stop intervals makes subtle adjustments in exposure or depth-of-field easy.

The Nokton lens is unusual in the rangefinder field because of the use of modern aspherical lens element fabrication technology on the rear element. The lens is constructed with two aspherical surfaces and one SD (super-low dispersion) glass element. This maintains the high level of image quality that rangefinder customers have become used to while keeping a highly competitive price point.
